Numismatist

At the beginning welcome all members of this forum, because I'm new. For this I'm Polish, I do not know English, so I use a translator.

Now I have a task called "numismatist". I'm at the stage where you have all questioned the circumstantial evidence of all, I now have the present stage "find numismatics." I'm going to the place where he shows me the minimap but there is nothing like that, no one, no issues or any NPC dialogue.
